Application file- September 29, 1920.

Be it .linown that ive, lnmn lll. liviix's and .inmunes A. Minnie, citizens of the lnited States. residing at Buffalo, in the countv of llrie end State of New York. have invented oei-tain new and useful improvements in lerosene-iurners, of which the follou'i is a. specification. l

lThis intention relates to imjjirovements in kerosene burners and its principal objects are to provide a simplyY and economically construeted burner available for either domestic or commercial applic tions and which, With n minimum consumption oi' kerosene und without liability of hack-lireT W'll give a relatifeljY high pressure. of n `food lfuel mixture with i resultunt hlue thune of intense strength.

The invention consists in certain t'eatures of structure and relation which will be detailed es the description proceeds and, geninvolves the combination of the burner head. the mixing pipe, the air and fuel inlets, and the pipe for conducting' n Huid medium heated b v the naines from the burner head to u point where seid inediuzn raises the temperature of the oil as it enters the mixing pipe.

In the accompanying drawing:

Figure l is e perspective vienv of :in od burner in which the features of the invention ure incorpointed.

Fig. a longitudinal section' of the is a section ou the line B- of rung-led in close sssociation substentiall)T throughout the ares of. the top oi the head;

the nipples 3 are provided with axial ducts cominunicatinp` with the interior of the head '1.

The fuel mixture is supplied to the hemd lA bv a cmiductinpl pipe J.- which extends over end somewhat close to said head and comnumieates therewith .at a .suitable point: 1e path or zone of PATENT GFFICE.

flames, and the mixture which flows ihreugh said pipe is maintained in gaseous state with its constituents thoneughlv coininineled. rl`he pipe 4 is, in factfzui elon- `gated mixing` chamber and in this capacitv is connected both with an oil and with aii air supply. the points of connection being Located beyond the flames and remote from the point at which said pipe is connected to may be mainthe owner head. The oil tained in an elevated tank (not shown) from which it flous by gravity under the control of a suitable valve (also not shown) as is wel. known in the art. The oil is conducted b v e pipe 5 to the aforesaid mixing chamber .-o1 "ituted h v the pipe l. The fuel mixture j. irtljg completed by air which is supplied ie pressure. 2'. e. from one to lve pounds from n tank or storage reservoir (not shown) through n. pipe 6.; said pipe has its outlet controlled by a suitable vulve T. prefereliljT n needle valvet and beyond and in continuation of said outlet is provided with un attenuated nozzle 8 Which projects into the end of the pipe 4:. across and beyond the outlet of the pipe 5. The end of the pipe 4 through which the nozzle n projects is suitably packed or sealed. The nir issues with considerable velocity from the nozzle 8 and takes up the oil supplied by the pipe the mixture flowing throughout. the length of the piIe 4L in Which it is subject to the heat of the flames. The uil' which issues from the pipe 8 effects the iorough zitomization of the oil und insures ie complete formation and gasification of ie mixture in the pipe 4.

The fuel mixture is mede readilyv grasi- :able h v utilizing a Huid medium heated h v the fames from the burner head to raise the temperature of the oil as it enters the mixing pipe 4.1. ln the construction shown end preferred this result is accomplished and the fuel mixture is completed by au additional supply of heated nir which enters the pipe 4 :it the same point :is the oil supplied hy the pipe 5 and beck of the discharge end of the nozzle 7, the latter preferably being thin-walled whereby it ma;r transmit heat to the air Within it. Such heated air is supplied by a pipe 9 which is connected to and projects at an angle from the pipe The pipe 9 extends over the llames so :is to he subject to the heet thereof and is prov'ded with e doivn-turned end il() through which the heated air enters. The

lovvio heated air through the pipe 9 is in- The init-'al heating of the mixture may be i effected in any suitable Way, for example, by

a priming jet or an electric coil (not shown) suitably arranged in relation to the nozzle 8 and the portion ofthe pipe l surrounding said nozzle, similar to the arrangement in common use for heating flowing currents oi"- liquid or gas.

Having fully described our invention ive claim: A'

l. In a kerosene burner, in combination, a hollow burner head having burner ducts, a mixing pipe arranged over and communicating with said head, a pipe tor air under pressure `having a nozzle communicating With said mixing pipe, an oilpipe communicating with said mixing pipe behind said nozzle, anda pipe :tor conducting a huid medium heated by the flames iirom said burner head to a point back of said nozzle Where it raises the temperature of the oil as it ent-ers said mixing pipe.

2. In a kerosene burner, in combination, a hollow burner head having burner ducts, a mixing pipe arranged over and communicating with said head, a pipe for air under pressure having a nozzle communicating with said mixing pipe, an oil pipe communicating With said mixing pipe behind said nozzle, and a pipe for conducting air heated by the flames from said burner head to said mixing pipe at a point back ot said nozzle mixing Where it raises the temperature ot the oil as it enters said mixing pipe.

3. In a kerosene burner, in combination, a hollow burner head having burner ducts, a

pipe arranged over and communicating with said head, a pipe for air under pressure having a nozzle vcommunicating with said mixing pipe, an oil pipe communicating With said mixing pipe behind Said nozzle,

y and apipe overhanging said burner head tor taking heated air from above the flames and conducting it to said mixing pipeat a point back of said nozzle where itraises the temperature ot the oil as it enters said mixing pipe.

4. In a kerosene burner, in combination, a hollow burner head having burner ducts, a mixing pipe arranged over and communicating 'with said head', av pipe for air under pressure having a nozzle communicating ivitli said mixing pipe, an oil pipe communicating with said mixing pipe behind said nozzle and a pipe communicating with and extending at an angle from said oil pipe iii overhanging relation to the burner head to convey heated air from above the flames to said oil pipe at a point ivhei'e it raises the tempeinture of the oil as it enters said mixing pipe.

In a kerosene burner, in combination, a burner head, a mixing pipe extending over and connected to the burner head, an oil supply pipe communicating ivith the mixing gipe, means for supplying air under pressure to the niixi pipe, and a pipe open to the atmosphere and having t-lie air column therein subject to the suction iniiuence created b v the escape of air under pressure into said mixing pipe, Said last named pipe being arranged to pass air heated by theflames to said mixing pipe.

6. In a kerosene burner, in combination, a burner hei-id. a mixing` pipe'conneeted to said burner head, an oil supply pipe communieating with the mixing pipe, means for supplying air under pressure to the mixing pipe, und a pipe open to the atmosphere and having the tion innuence created by the escape of air under pressure into said mixing pipe, said last named pige being arranged to pass air heated by the ianies to the mixing pipe.

7. In a kerosene burner, in combination, a burner head, a. mixing pipe connected to the burner head, :in oil supply pipe communicating with the mixing pipe, means for supplying air under pressure to the mixing pipe, and a pipe open to the atmosphere and extending over the burner head with its open end down-turned to take air from above the llames, said lastnamed pipe having its air column subject to the suction intluence created by the escape ot a ir under pressure into sai-d mixing pipe and passing heated air into sain mixing pipe.

S. In a kerosene burner, in combination, a burner 'head` a mixing pipe extending over and connected to the burner head, an oil supply pipe communicating with the mixing pipe, means for supplying air under pressure to the mixing pipe, and a pipe for conducting a fluid medium heated by the {iames ii'oin said burner head to a point Where it raises the temperature of the oil as it enters said mixing pipe.

In testimony whereof` ive aiiix our signatures.
